Acast

Acast is a podcast hosting, distribution, and advertising marketplace that helps creators publish shows, distribute to every major listening platform, and monetize through dynamic ad insertion and sponsorships. Acast exposes a documented public Publishing API for programmatically managing shows and episodes - listing shows and episodes, fetching details, and creating, updating, and deleting episodes - plus placing ad markers and receiving webhook notifications for events like new episode publications. The API is documented openly at developers.acast.com, but access is gated - an X-API-Key credential is issued by Acast's customer success team to accounts on the Ace plan or in the Acast Creator Network.

Acast publishes 3 APIs on the APIs.io network: Ad Markers API, Episodes API, and Shows API. Tagged areas include Podcasting, Podcast Hosting, Publishing, Advertising, and Monetization.

Acast’s developer surface includes authentication, documentation, and 8 more developer resources.

Where this information came from

This is an independent, third-party profile of Acast, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
